Hello Spameden, Thanks you for your response, I m totally agree with you but unfortunately I have no possibility to use OpenVPN tunnel, it s a decision of security team (many complicated reasons unfortunately). My idea is to convert smpp to http (via kannel) and redirect the http to https (via nginx). That's why I need to connect 2 kannel instancies. I didn't describe the https redirection to simplify the euse case. finally : smpp --> http --> https ------------>https --> http --> smpp : I want to recover the same initial message without any change (deliver-sm must be keeped deliver_sm and the same think for de submit_sm)
I hope it is more clear Thanks a lot. 2013/8/27 spameden <[email protected]> > > > > 2013/8/27 Ahmed ben ali <[email protected]> > >> Hello, >> >> I explain my need : >> I have 2 sites interconnected by a private network, and encryption is not >> possible on this network (for many reasons).
